Gotcha, yes, I dug around in the Parser.pm to have a look at that sort of stuff. For example, here is the part dealing with binary attachments:

$bin_ent->head->mime_attr('Content-type.x-unix-mode' => "0$mode");
$bin_ent->bodyhandle($self->new_body_for($bin_ent->head));
$bin_ent->bodyhandle->binmode(1) or die "$ME: can't set to binmode: $!
+";
my $io = $bin_ent->bodyhandle->open("w") or die "$ME: can't create: $!
+";
$io->print($bin_data) or die "$ME: can't print: $!";
$io->close or die "$ME: can't close: $!";

And here is the part dealing with text attachments:

$txt_ent->bodyhandle($self->new_body_for($txt_ent->head));
my $io = $txt_ent->bodyhandle->open("w") or die "$ME: can't create: $!
+";
$io->print(@$preamble) or die "$ME: can't print: $!";
$io->close or die "$ME: can't close: $!";

So it occurred to me: "Hmm! If I add in code to force the text to use binary like this..."

$txt_ent->bodyhandle($self->new_body_for($txt_ent->head));
$txt_ent->bodyhandle->binmode(1) or die "$ME: can't set to binmode: $!
+";
my $io = $txt_ent->bodyhandle->open("w") or die "$ME: can't create: $!
+";

Unfortunately it didn't work, leading me to conclude that I don't know enough about the code at this time to be dealing with changing the guts of an existing perl module.

Technically I could copy and recreate it under the name of MIME::MyParser and see if I could manage to hack that into submission - however it seemed more than I was capable of managing if I couldn't even change the existing code. It was at this point that I decided it was easier to hack the input-file to trick the parser into doing what I want it to do.
